MACHINE FOR STRINGIN G UP TOBACCO-LEAVES.

"application filed August 16, 1906. Serial No. 330,915.

, 'Radolfzell, in the Grand Dukedom of Baden,

Germany, have invented certain new and useful Improvements in a Machine for Stringing Up Tobacco-Leaves; and wedo hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the stringing of tobacco and'has for its object the provision of means for mechanicallydistributing the tobacco so as to drying.

, The invention, as hereinafter particularly set out in the claims, will be more fully deobtain positive and uniform scribed in connection with the accompanying drawing, illustrating one embodiment of the same, in which drawing,

Figure 1 is a transverse section; Fig. 2 is a longitudinal section; Fig. 3 is a top plan;

and Figs. 4 and 5 are detail sections at right angles to each other through one of the tobacco retaining cells and needle.

Referring to the drawing in detail, the table a is supported on the stand I) likewise 30. bearing at one side and. parallel to the table a frame 0. In the frame and dyieldingly sup- .gqrted by springs d are sli ably mounted locks e separated from each other. by ribs f dividing the face of the frame into a series of Each block ispr'cvided on its u per face with a groove, preferably V-shape in cross-section, extend- I 1ng transversely ofthe frame and adapted to receive the stem of the tobacco leaf lying on 40 the table.

Bevel gears g and h serve to drive toothed pinions 01 arranged at intervals in the frame a and dividing the tobacco receiving, cells into roups. These pinions mesh with a rack ormed along the edge of a needle is and serve to propel the same longitudinally of the series I of cells together with its cord.

A series of plates Z mounted on a common rod 9 are arranged one over each block entlo e blocks e and the plates [are provided on their opposingfaces with a-groove extending transversely of the frame and adapted to receive-the stem of the tobacco leaf lying on the table a. The opposing'faces of the .blocks 0 and plates 1 are likewise provided ing extending longitu with recesses which togetheirforf'm fitn fopen-i inal yao t e ra'rne Specification oil-Letters Patent.

and the openings in the several blocks a d...-

plates constitute a passage for the needle the full length of, the frame andintersectingthe transverse grooves in each holder.

In operationythe tob. coo leavesal'ear ranged on the table a wit their stems in the} respective grooves inthe blocks e. The

plates Z are then brought down to clamp the.

stems in the grooves. By foot pressure on the treadle .m the chainn 'rotates'the sprocket gear p and thegear wheels 0 drive the shaft r and with it the bevel gears. g and h and the pinions '5, whereby the needl'e k with itscord- 1s projected throu h the longitudinalpassage in the tobacco holderarpiercing' the ster'n of each leaf in succession and threading them on the cord as will be readil understood. The pressure of the foot weight 8 reverses the operation, and, the lates Z on the rod 9 being lifted, the strun leaves are easily removed. and others place in'position. i r v Having thus fully descriied our invention, what we claim is; I

l. The combination, tf holders arranged in seiies, a needle arranged to traverse the holders'in linewith the-leaves and having its side formedfas a rack, and a eing released, the

plurality of lee drive pinion, meshing with the rack to propel 4 the needle through the holders.

2. The combina tion, of'a plurality of leaf holders arranged in series, a comparatively short needle arranged to traverse the holders in line with the leaves, and having its side formed as-a rack, and a plurality of spaced one in each cell and comprising an underlying spring-pressed block and an overlyingl plate, a 'need e arranged to traverse the olders between the blocks and plates and transfix as a rack, and a plurality of spaced drive pinions arran ed to successively mes'h .P I 'gressively propel the nee le through 'the' the rack of t e advancin needle to holders.

into a series of cells, a plurality of leaf hold ers propel the j 4. The combination, of -a frame 110 the leaves, said needle having its side formed onein each cell andeompnsmg' an underlyeing spring-pressed Mel; and an. overlying.

opposing plate, the blocks and plates provided in their faces with transverse grooves to receive the leaf stems and with longitudinal grooves to form a needle passage, a needle arranged to traverse the said passage and transfix'thc stems, said needle having its side formed as a rack, and a plurality of drive pinions arranged at intervals to successively mesh with the rack of the advancing needle to propel the needle progressively forward.

5. The combination, of a frame divided into a series of cells, a plurality of leaf holders one in each cell, and comprising an underlying spring-pressed block and an overlying plate, the blocks and plates provided'in their opposing faces with transverse grooves to receive the leaf stems and with longitudinal grooves to form a needle passage, a needle arranged to traverse the said. passage and transfix the stems, said needle having its side formed as arack, a plurality of drive pinions arranged at intervals to successively mesh with the rack of the advancing needle to propel the needle progressively forward, a foot treadle, a drive shaft actuated thereby, and hevel gears connecting the drive shaft with the drive pinions to effect simultaneous movement thereof.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
